SPECIFIOATION forming part of Letters Patent No. 598,930, dated February 15, 1898. Application filed April 24,1897. Serial No. 633,817. (No model.)

To all whom it may concern/.

Be it known that I, GEORGE HENNING, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Glass-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in glass-presses of the power-operated class, the object being to secure increased efficiency of operation; and it consists in the novel features of construction, combination, and arrangement of parts, as hereinafter fully described, and specifically pointed out in the claims.

In the drawings, Figure 1 represents a front elevation of a press embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a detached view of the plunger-slide; Fig. 4, a side view of the eccentric and connections for moving the cap-plate. Fig. 5 is a plan view of the gearing, &c., below the bed of the machine.

In the drawings, A represents the bed of the press, supported on or forming part of a truck-frame a, provided with wheels 0, for readily moving the press about. Upon the bed A are supported the upright rods or pillars b b, maintained in true position and alinement by braces c. The rods 1) 6 form guides for a yoke or cross-head D, connected by rods 6 e to cranks E on a shaft F, journaled in the frame a. Asecond cross-head G, connected to yoke D, slides on the pillars b, being placed below the yoke D, and carries a slide g, to which are secured two or more plungers H in the manner presently to be described. A pulley f on a shaft 2 is belted or otherwise suitably connected to a source of power, as a line-shaft pulley or the like, and being geared by a suitable train of gears, as 6 '7 8 9, to the shaft F serves to continuously rotate the same, the usual belt-shiftin g device in common use being also provided for stopping the machine'at any moment. Obviously each revolution of shaft F will cause the yoke D, cross-head G, and plunger H to descend and rise once.

\ The slide g moves freely on the cross-head G, preferably on ball-bearings, and carries on its under side two chucks i a, through which a right-and-left screw 2' passes and serves to clamp the plunger H firmly in the chuck, thus enabling the pl ungers to be quickly changed.

An air-pipe J extends down on each side of the rod b on each side of the press and is affixed rigidly to the press by suitable means such, for instance, as the bars 6 secured to the pipes J and rods 19. The pipes J termi nate above the cross-head G and receive pipes j, which are sleeved in the pipes J and slide freely but not loosely therein. The pipes j are secured firmly to the cross-head G and move therewith and at their lower ends are provided with tips or nozzles 7' which aredirected toward the points occupied by the plungers H H when at the outward limit of their travel, as shown. A blast of air, artificially cooled or not, as may be preferred, is forced through the pipes J], &c., and impinging directly on the plungers keeps them from becoming heated by the hot glass.

Attached to slide gis a slotted or grooved plate 9 in which plays a pin on an arm K, which is rigid with a short shaft 5, supported in a bearing on the bed A and having an arm K which forms substantiallya continuation of arm K and extends below the bed A, carrying at its lowerend a second pin 70 which engages a cam-groove m on a drum or disk M. The arms K and K thus act substantially as alever pivoted on shaft Z. The drum M might be carried by the shaft F, but I prefer to place it on an auxiliary shaft n, suitably supported, and which carries also a gear 0, meshing with a gear or pinion 0 on the shaft F. By thus placing the drum on a separate shaft it may be made smaller, the cam-groove simpler, and can also be rotated at a different rate of speed from that of shaft F, preferably at one-half the speed of shaft F. The pins. 70 70 are'preferably provided with rollers k journaled thereon, to reduce the friction.

An adjusting-screw 10 is aflixed to the crosshead G and threaded through an adj usting-- nut 10, seating upon the yoke D, screw 12 carrying intermediately a nut 19 between which and the yoke is interposed a heavy bufferspring 19 By this screw the throw of the plungers is regulated.

An eccentric Q on shaft F reciprocates a rod g, which plays in a guide r and is attached to a cross-arm S. The cap-plate t of the mold T is connected by rods U at each end to the corresponding ends of the cross-arm S, the rods U passing through the bed A and carrying springs to, interposed between the plate t and bed A, as shown.

The operation of the machine is as follows Assuming the mold T to be in place and filled with molten glass, the rotation of shaft F by pulley f and their connecting train of gears will first cause the cam Q to draw down the cap-plate if, its projection 75 seating in a corresponding recess in the mold. The further rotation of shaft F will next cause the cranks E, which have meanwhile been drawing down the rods 6, yoke D, cross-head G, and plungers II, to force the plunger which occupies the central position to enter the mold and form the article. Then as the cranks E continue their revolution they lift the plunger, and as it rises above the cap-plate t the pin which has meantime been traveling in the straight part of the cam-groove m on the continuouslyrotating drum M, now strikes the inclined part of the groove and moves the arms K and K laterally, which, by means of the pin is travelin g in plate 9 moves the slide 9 along crosshead G, so as to bring the second plunger in the center and in line with the mold, which has in the meantime been removed, emptied, refilled, and replaced, the plungers thus actin g altern ately and always in the center, which prevents lateral strains on any of the parts. As the air-pipes j and their-nozzles travel withthe cross-head,the plunger not acting is always being cooled and each plunger is subject to the cooling-blast about three-quarters of the time, which entirely prevents the overheating of the plunger.

Obviously the plungers could be arranged to travel in a line at any angle to the lateral. line shown or in a circle without departing from my invention, which, as regards this feature, consists, broadly, in employing a plurality of plungers which act successively and are subjected to cooling means while inactive or not in operation.
